Application of ZnCl2 soldering acid and Sn-Pb filler metal is a traditional restoration method for bronze ancients. Because this soldering acid contains Cl-, it is harmful to the conservation of ancient bronze. In this paper, a new type soldering acid and Sn-Pb-Ag filler metal for restoration of ancient bronze have been studied by screening and selection. A series of material performance test results have showed that the application of new soldering method has the most anti-corrosive characteristic and soldering welability. Soldering joints remain bright and have an excellent connection for different ancient bronze. Bronze are kept for in half a year after soldering, corrosion phenomenon would not be found surrounding the solder joint. Applications of new type soldering acid and Sn-Pb-Ag filler metal have replaced traditional ZnCl2 soldering acid and Sn-Pb filler metal in the restoration of ancient bronze, which conform with conservation principle of culture relics and have no effect on operator in soldering process.
